  • a web service can be provided to various multimedia appliances compatible with the smart card 200 regardless of the existence of the browser on the user terminal 100 and the type and version of the browser.
  • the method and steps of the algorithm described above related to the embodiments of the present invention may be realized in the form of hardware, software executed by a processor, or combination of the hardware and software.
  • the software module may reside in a storage medium, such as a RAM memory, a flash memory, a ROM memory, an EPROM memory, an EEPROM memory, registers, a hard disc, a mobile disc, a CD-ROM, or other storage devices generally known in the art.
  • the storage medium is connected to the processor, so that the processor may read information from the storage medium or record the information onto the storage medium.
  • the storage medium can be integrated in the processor.
  • the processor and the storage medium may be included in an ASIC.
  • the ASIC may be included in the terminal.
  • the processor and the storage medium may serve as components of the terminal.
  • the smart card-based browsing system, the smart card-based browsing method, and the smart card for the same of the embodiments of the present invention are distinguished from the conventional technology in that a browser (HTTP Client) is installed in the smart card so that a direction connection path with the SCWS can be established. Accordingly, the present invention can be made sufficiently available on the related market and in business, and can be utilized in practice, thus the present invention has industrial applicability.
